The key 12 is cirthe possession of the nurse or atten ant. cular and larger diametrically than the flange With the foregoing and other objects in 5, and is provided with a depending annular 65 view, the invention consists of the construcflange 13 which surrounds the flange 5 on the tion, combination and arrangement of parts app ication of the key to the plug 7 and which .hereinafter fully described and claimed, and constitutes a grip through the medium of illustrated in the accompanying drawing, which the key may be held firmly during the wherein: application and removal of the plug. To es- 70 Figure 1 is a view in side elevation of a tablish an operative connection between the fra mentary portion of an ice-bag equipped key 12 and lplug 7, the former is provided with with aclosure constructed in accordance with downward y eXtending lugs 14 which are my invention, the key for the closure being adapted to engage in the recesses 11.

omitted, As the plug 7 cannot be removed from the 75 Figure 2 is a top plan view of the ice-bag ice-bag 1 without the aid of the key 12, which and closure, should always be in the possession of the nurse YFigure 3 is a sectional view taken on `the 0r attendant, it is impossible for a patient to plane indicated by the line 3-3 of Figure 2, gain access to the contents of the bag during Figure 4 is a similar view with the key apthe absence of the nurse or attendant. The 80 plied, closure and its key may be manufactured at a Figure 5 is a bottom plan view of the key, Comparative] low cost, the former may be u and readily insta led in the ice-bag, and the lat- 30 Figure 6 is a sectional View taken 0n the ter may be readily applied to and removed plane indicated by the line 6-6 of Figure 5. from the former. 85 Referring to the'drawing by reference nu- It should be understood that the drawing merels, 1 designates the body and 2 the neck 1s merely illustrative and does not pretend to of an ice-bag which may be of any well known give exact proportions. Furthermore, the or appropriate construction. said drawingv is illustrative of a preferred he closure for the ice-ba I comprises a construction, it being my expectation that 90 4` sleeve 3 which is screw threa ed and suitably Various Changes und mOdiCMOIIS .my be secured within the neck 2. The sleeve?, is pro-. made without departing from the spirit and vided at its upper end with a radial flange 4 scope of my invention. While the closure is and an axial flange 5. The flanges 4 and 5 are shown and described in connection with an iceannular, the flange 4 is provided in its lower bag, it is to be understood that it is not limited 95 side with an annular groove 6 for the recepto this particular use as it is adapted to and tion of the upper end of the neck 2, and the will be used in connection with hot water flange 5 extends upwardly from the outer bags and the like.

4 edge of the flange 4. A plu 7 is threaded in What is claimed is the sleeve 3, and is provide at its upper end A closure for a bag provided with a neck, 1.00

with a radial flange 8 which overlies the flange comprising a screw threaded sleeve secured 4. A gasket 9 is positioned between thelanges ".within the neck, an annular flange extending 4 and 8 to render the closure water-tight, and outwardly from the upper end of the sleeve the flange 8 is provided in its under side with and provided in its lower side with an annuanv annular groove 10 for the reception of the lar groove for the reception of the upper e'nd 105 gasket. The upper end of the plug 7 and the of the neck, a screw threaded plug engaged in flange 8 occupy, when the plug 1s in fully the sleeve and provided at its upper end with closed position, a position within the flange 5 an outwardly extending annular flange over- 2 y 1,712,861 lying said first flange and provided in its flan e,said last Hangs surroundi the lower side with an annular groove, a gasket ont eplug and extending abovet eplug and positioned between said flanges and arran d 1n the groove of said second flange, the p ug 5 being provided in its upper end with key en aging recesses, and an annular Han e extendits flange to prevent the plug flange from be- 10 ing upwardly Ifrom the outer edge o said first grasped 1n theI hand. n testimony whereof I aix my signature.
